SWITCH-STAND.

Specification ofLetters Batent.

Patented Dec. 28, 1920.

Application filed May 27, 1920. Serial No. 384,666.

To all whom it may concern:

Be it known that I, WILLIAM D. INGLE, a citizen of the United States, residing at Oakland City, in the county of Gibson and State of Indiana, have invented new and useful Improvements in Switch-Stands, of which the following is a specification.

This invention relates to railroads, particularly to switch stands, and has for its object the provision of a novelly constructed switch stand which includes an inclosed spring which is for the purpose of completing the throwing of the switch point when the operator moves the actuating lever a certain extent. I

An important object is the provision of a device of this character which is readily associated with a switch point and which lies below the level of the track with the exception of the operating handle which naturally extends thereabove.

A further and more-specific object is the provision of a device of this character which is so constructed that the spring will operate not only to throw but also to hold the pivoted parts past center so that retrograde movement will be prevented.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, easy in installation, eflicient in use, durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which Figure 1 is a plan view of my device showing it associated with the switch points of a railroad,

Fig. 2 is a side elevation of my device alone,

Fig. 3 is a detail longitudinal sectional view through my device, and

Fig. 4- is a cross sectional view therethrough on the line 4-4.- of Fig. 2.

Referring more particularly to the drawings, the letter A designates the rails of a trackway including the usual ties B. The letter C designates the usual switch points which are connected for simultaneous movement by a bar D extending beneath the rails.

In carrying out my invention I provide a supporting bracket designated broadly by the numeral 10 and including a horizontal spaced ears 24.

flat plate 11 and a U-shaped plate 12 which has the ends of its arms out-turned, as shown able within the sleeve 17 is a sleeve 22 provided at its outer end with an inturned flange 23 and carrying at the same end A coil spring 25 is disposed within the sleeve 22 and has one end abutting against the flange 23 and its other end abuttingagainst the transverse bolt 19. The purpose of this spring is to urge the sleeve 22 out of the sleeve 17.

Pivoted through the plates 11 and 12 of the supporting bracket is a vertical shaft 26 which may have its upper end provided. with any suitable handle, not shown, and this end is preferably squared, as shown at 27 for this purpose. Between the plates 11 and 12, the shaft 26 carries an arm 28 which is rigidly secured upon the shaft and which has its free end disposed between the cars- 24 and pivoted thereto by a bolt 29.

My device is connected with the switch points by means of a link 30 having a forked end 31 pivoted upon the. bolt 29.

In the operation of the device, assuming that the parts are in the position shown in Fig. 1, when it is desired to throw the switch to open the main line, it is merely necessary that the operator turn the shaft 26, through the instrumentality of whatever handle may be provided, through a sufficient arc to bring the pivot point 29 past center with respect to the pivot points 15 and 26. As this movement occurs, the sleeve 22 is telescoped into the sleeve 17, resulting in compression of the spring 25. As soon as the pivot point 29 is past center and the operator releases the handle, it will be seen that the spring will operate to force the sleeve 22 out of the sleeve 17 and this will result in completing the throw. As the sleeve 17 is pivoted intermediate its ends and as the free end is connected with the link 30 connected with the bar D connecting the switch points, it will be seen that the switch points will be thrown.

claim:

WVhen it is desired to open the switch the shaft 26 is rotated in the'opposite direction and the reverse movement will occur, y 7 From the foregolng descrlption and a study of the drawings it will be apparent that I have thus provided a simply constructed and yet highly efficient switch stand which will insure completionof the throw of the. switch points even though the operator might carelessly neglect to move the operat- 7 ing handle. to its maximum extent.

NVhile I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts as will not depart from the. spirit of the invention or the scopeof the subjoined claims.

Having thus described my invention, I

1. In combination with the movable switch points of a railroad track, the switch points being connected by a bridle bar, a

saidbracket and carrying an arm,a sleeve member pivoted within said bracket, a second sleeve slidable within said first named V sleeve and pivotally connected at its free end with said arm and with said bar, and a spring disposed w1th1n said sleeves and normally tending to move sald second named sleeve outwardly from the first named sleeve. '2. In combination with the ,movable switch points of a railroad track, the switch points being connected by a bridle bar, a switch stand comprising a supporting bracket including a fiat plate and a U-shaped plate secured upon the underside thereof and having the ends of its arms out-turned and secured upon the ties, an operating shaft journaled through said plates and carrying an arm between said plates, a collar pivoted between said plates, a sleeve extending through said collar and having a retaining flange engaging thereagainst, a transverse bolt passing through the other end of said sleeve, a second sleeve slidable within said first named sleeve and having its outer end formed with spaced 'earsand an inwardly extending flange, said arm being pivoted between said ears, said bar being pivoted at said connection, and a spring disposed within said sleeves and having one end engaging said bolt and its other end engaging said inturned flange.

. In testimony whereof I aflix my signature.
